CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 472,992, dated April 19, 1892.

' Application filed January 8, 1892- Serial No. 417,409. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES GESOHWIND- NER, of Brooklyn, New York, have invented an Improved Car-Coupler, of which the followtures of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of the coupler, showing it closed, Fig. 2, asimilar section showing it open. Fig. 3 is a top View thereof, and Fig. 4 a perspective of the sleeve.

The letters (1. represent two adjoining cars provided with bearings 19, in which turn rockshafts c. The ends 0 of these shafts are bent at right angles and carry weights c Each rock-shaft c is surrounded by a freelyvturning sleeve d, which is slotted, as at d, for

the reception of a pin cisecnred to rock-shaft c. The sleeve d is provided with a slotted link (1 that engages a pin 8 on the couplinghook e. by a forked bracket f bolted to the car a.

The rock-shafts 0 may be revolved backward or forward from the car-platforms by means of a suitable chain gor similar attachment. When the shafts c are rocked backward, Fig. 1, the links (1 will be raised and the hooks e swung down. When the shafts c are rocked forward, Fig. 2, the links (1 will be lowered and the hooks e swung up. The motion of the rock-shaft is in both cases imparted to the sleeve 61 by the pin 0 21s soon as such pin engages either the front or rear edge of the slot d. Until such engagement takes place the shaft rocks without taking This hook turns upon a pin f, held the shaft. 7

In use the shaft 0' is swung backward, Fig. 1, to bring the hooks down and then the cars are pushed together, when the hooks will automatically engage the pins v f and couple the cars. In this position the pins 0 bear upon the rear of the slots d, and the rockshafts thus tend to hold the hooks firmly coupled.' When the train has about completed its journey and nears the terminal depot, the shafts o are swung forward, so that pins 0 bear upon the front'of theslots d and the rock-shafts tend to open the hooks- In this position of the shafts, however, the hooks will still maintain their engagement with the pins f as long as there is apull on the train; but as soon as such pull ceases and the cars are slightly backed together, so that the hooks release their hold on the pins, the weights 0 will drop down, Fig. 2, thus swinging the hooks up and uncoupling the cars.

In case it is desired to uncouple the cars without first backing them together the hooks may be readily raised off their pins by hand.

It will be seen that this coupling is of simple construction and can be readily opened and closed.

What I claim is 1. The combination of rock-shafts c with sleeves d, mounted upon the same and having slotted arms (1 and with hooks e, engaged by such arms, and. pins f, engaged by the hooks, substantially'as specified.

2. The combination of weighted rock-shaft 0, having pin c ,'with slotted sleeve (1, engaged by said pin and having slotted arm d and with hook e and pin f, substantially as specified. t
